AIS gap
No further position was observed for the detection interval in an area with established AIS reception. This observation does not establish why the signal was lost.
Last signal before gap: 2026-10-20 02:58:16 UTC · Reception in preceding 24 h: 24 h · Last reported speed: 7.6 kn
-
Infrastructure proximity
The vessel was observed slow or stationary near a mapped cable or pipeline corridor. Routes can be approximate, and proximity alone does not show contact or damage.
First observation: 2026-10-20 01:07:48 UTC · Observed duration: 30 min · Closest observed separation: 5 m
-
Signal returned
A position was observed after a prolonged AIS gap. The recorded distance is between the last and returning observations, not a known route through the gap.
